This is an industrial USB to RS485 bidirectional converter with original FT232RL and SP485EEN inside. It features embedded protection circuits such as lightningproof, resettable fuse, ESD protection, and TVS diode, etc. It's pretty small in size. The USB TO RS485 is very easy to use, allows automatic transceiving. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement. Features- USB to RS485 communication
- Adopt original FT232RL and SP485EEN, fast communicating, stable and reliable, better compatibility
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
- Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
- 3 LEDs for indicating the power and transceiver status
